Geometrically calibrating a device is not just a simple matter of running an image of a checkerboard through Imatest software. It requires prior information about the nominal device specification and a considered test setup appropriate to the device. In return, Imatest can produce consistent and accurate calibrations even for challenging devices in a constrained setting (such as a production line).

Designing a calibration program for your device

Before you are able to make proper, accurate use of the Geometric Calibrator, you should:

Determine your accuracy requirement for the parameters to be calibrated.

Gather the nominal device specification values for your system, including the field of view for all devices, hyperfocal distance, and sensor pitch.
